== HTTP Tracing
You can enable HTTP Tracing by providing a bean of type `HttpTraceRepository` in your application's configuration.
For convenience, Spring Boot offers `InMemoryHttpTraceRepository`, which stores traces for the last 100 (the default) request-response exchanges.
`InMemoryHttpTraceRepository` is limited compared to other tracing solutions, and we recommend using it only for development environments.
For production environments, we recommend using a production-ready tracing or observability solution, such as Zipkin or Spring Cloud Sleuth.
Alternatively, you can create your own `HttpTraceRepository`.

You can use the `httptrace` endpoint to obtain information about the request-response exchanges that are stored in the `HttpTraceRepository`.



[[actuator.tracing.custom]]
=== Custom HTTP tracing
To customize the items that are included in each trace, use the configprop:management.trace.http.include[] configuration property.
For advanced customization, consider registering your own `HttpExchangeTracer` implementation.
